Dear list, I cannot compile a simple example using the subgraph implementation. I enclosed the code in the bottom of this email. It is quite short, but it is the whole code. It does not compile with errors from inside boost/graph/detail/adjacency_list.hpp about the impossiblity of making a reference to void. I read the subgraph documentation but I cannot understand why it does not work. Can anyone enlighten me? Your faithfully, Paolo The code: ------------------ >8 #include <boost/graph/adjacency_list.hpp> #include <boost/graph/subgraph.hpp> typedef boost::adjacency_list < boost::listS, boost::listS, boost::undirectedS
main_graph;
typedef boost::subgraph <main_graph> sub_graph; typedef boost::graph_traits<sub_graph>::vertex_descriptor Bvertex; 8< ------------------
